FAQs on Past Year Paper, Physics (Set - 3), 2015, Class 11, Physics - Additional Study Material for NEET

1. What are the fundamental principles of physics?
Ans. The fundamental principles of physics include the laws of motion, conservation of energy, conservation of momentum, and the theory of relativity. These principles provide the foundation for understanding and explaining the behavior of matter and energy in the universe.
2. How does Newton's law of motion apply to everyday life?
Ans. Newton's law of motion applies to everyday life in various ways. For example, the first law of motion explains why objects at rest tend to stay at rest, and objects in motion tend to stay in motion unless acted upon by an external force. This principle is seen when a car abruptly stops and the passengers continue to move forward due to inertia.
3. What is the difference between potential energy and kinetic energy?
Ans. Potential energy is the energy possessed by an object due to its position or condition, while kinetic energy is the energy possessed by an object due to its motion. Potential energy can be converted into kinetic energy and vice versa, as demonstrated by a roller coaster ride where potential energy is converted into kinetic energy as the coaster moves downhill.
4. How does the theory of relativity impact our understanding of space and time?
Ans. The theory of relativity, proposed by Albert Einstein, revolutionized our understanding of space and time. It states that the laws of physics are the same for all observers, regardless of their relative motion. This theory also predicts that time can be influenced by gravity and that objects with mass can warp the fabric of spacetime.
5. What is the significance of conservation laws in physics?
Ans. Conservation laws, such as the conservation of energy and the conservation of momentum, are fundamental principles in physics. They state that certain quantities, such as energy and momentum, remain constant in a closed system, even though they can be transformed from one form to another. These laws provide a framework for understanding and predicting the behavior of physical systems.
